Merge branch 'timers-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip into next

Pull timer core updates from Thomas Gleixner:
 "This time you get nothing really exciting:
   - A huge update to the sh* clocksource drivers
   - Support for two more ARM SoCs
   - Removal of the deprecated setup_sched_clock() API
   - The usual pile of fixlets all over the place"
